Description

Wärmeaustauscher, insbesondere Heizkörper, bestehend aus einem Rohr und auf dessen Oberfläche mit ihren Hohlseiten einander zugekehrten, paarweise angeordneten, konischen Scheiben Wärmeaustauscher, insbesondere Heizkörper, bestehend aus einem Rohr, und auf diesem aufgetriebene Scheiben, die konische Form besitzen und paarweise mit den gegenseitigen Hohlseiten einander zugekehrt 23 sind, sind bekannt.Heat exchangers, in particular radiators, consisting of a tube and on its surface with their hollow sides facing each other, arranged in pairs, conical disks heat exchangers, in particular radiators, consisting of a Tube, and on this expanded disks which have a conical shape and are in pairs with the mutual hollow sides facing one another 23 are known.

Diese Rippen mußten bisher aufgeschweigt werden. Sieht man von dem Schweißen ab, so ist oder wird mit der Zeit der Kontakt zwischen den zentrischen Lochungen der Scheiben und dem Rohr zu gerin 9, um Wärine ohne merkbaren Verlust zu übertragen.Until now, these ribs had to be kept silent. If one disregards the welding, the contact between the centric perforations of the washers and the tube is or will be reduced over time in order to transfer heat without noticeable loss.

Die vorliegende Erfindung trägt dem dadurch Rechnung, daß die mit ihren Hohlseiten einander zugekehrteil konischen Scheiben von beiden Enden her in axialer Richtung einem Druck: unterliegen. Die Scheiben können an ihren Rändern gewellt sein. Sie können in an sich bekannter Weise Durchbrechtingen aufweisen und sind zweckmäßig durch Muffen an den Endscheiben gegeneinandergedrückt.The present invention takes this into account in that the with their hollow sides facing each other in conical discs from both ends axial direction a pressure: subject. The discs can be on their edges be wavy. They can have breakthroughs in a manner known per se and are expediently pressed against one another by sleeves on the end plates.

Die Zeichnung zeigt eine Ausführungsforrn des erfindungsgemäßen Wärmeaustauschers, und zwar Fig. 1 im Aufriß, teilweise im Schnitt, Fig. 2 in Stirnansicht.The drawing shows an embodiment of the heat exchanger according to the invention, namely FIG. 1 in elevation, partially in section, FIG. 2 in front view.

Auf ein Rohr 1 aus Metall sind 1,onische Metallscheiben 2 aufgeschoben, und zwar paarweise, derart, daß die Hohlseiten der Scheiben 2 einander zugekehrt sind. Die Scheiben 2 bestehen aus federndem Material und sind zwischen Muffen 3 und 4 gehalten und zusammengepreßt. Die Scheiben besitzen Naben 5, die axial geschlitzt sein können und auf dem Rohr 1 aufliegen.On a tube 1 made of metal 1, onic metal disks 2 are pushed, in pairs, in such a way that the hollow sides of the disks 2 face each other. The discs 2 are made of resilient material and are held between sleeves 3 and 4 and pressed together. The disks have hubs 5 which can be axially slotted and which rest on the tube 1.

Der gegenseitige Andruck, hervorgerufen durch die Muffen 3 und 4 oder die Stäbe 6 mit Muttern 7 bewirkt, daß die Naben 5 bestrebt sind, sich der Oberfläche des Rohres 1 zu nähern, so daß stets ein guter Kontakt zwischen den Naben 5 und dem Rohr 1 vorliegt. Die Scheiben können, wie gezeichnet, mit Durchbrechungen versehen sein, um auch die Innenseite eines Scheibenpaares für die Wärme- oder Kälteabgabe nutzbar zu machen.The mutual pressure caused by the sleeves 3 and 4 or the rods 6 with nuts 7 causes the hubs 5 to tend to approach the surface of the tube 1 , so that there is always good contact between the hubs 5 and the tube 1 is present. As shown, the panes can be provided with perforations in order to make the inside of a pair of panes usable for the release of heat or cold.

Wesentlich ist, daß die Scheibenpaare, voll denen mehrere vorliegen können, einem axialen Druck unterliegen, so daß selbst im Falle der Längenausdehnung des Rohres 1 ein guter Wärmekontakt zwischen den Naben 5 und dem Rohr verbleibt. Zufolge der Elastizität paßt sich die Gesamtrippe der durch die erhöhte Temperatur bedingten Längenausdehnung des Roh-res 1 an.It is essential that the pairs of disks, full of which there can be several, are subject to an axial pressure, so that even in the event of the tube 1 expanding in length, good thermal contact remains between the hubs 5 and the tube. According to the elasticity, the total rib caused by the elevated temperature linear expansion of the raw fits res 1 to.

Die Scheiben sind einfach auf dem Stanzwege herzustellen und sind alle gleich, so daß die Herstellun,gskosten verhältnismäßig gering sind. Das Aufschieben auf das Rohr 1 bringt keine besonderen Schwierigkeiten. Die Scheiben 2 mit gleichem Lochdurchmesser können sogar, wenn die Durchmesserdifferenz nicht zu groß ist, auf Rohre 1 verschiedenen Durchmessers aufgeschoben werden. Wenn der gegenseitige Andruck genügend groß ist, liegt auch bei einem etwas verringerten Querschnitt des Rohres 1 ein guter Kontakt vor. Die gegenseitige Abstützung der Scheiben 2 bedingt, selbst wenn die Scheiben aus sehr dünnem Blechmaterial bestehen, eine hohe Stabilität.The disks are easy to manufacture by punching and are all the same, so that the manufacturing costs are relatively low. Sliding onto the pipe 1 does not cause any particular difficulties. The disks 2 with the same hole diameter can even be pushed onto tubes 1 of different diameters if the difference in diameter is not too great. If the mutual pressure is sufficiently great, there is good contact even with a somewhat reduced cross-section of the tube 1. The mutual support of the disks 2 requires a high level of stability, even if the disks are made of very thin sheet metal material.

Wenn die einzelnen Metallscheiben nicht federnd oder elastisch sind, dann können zwischen die Muffen 3 und 4, die Schraubmuffen sein können, und den Scheiben2 Schraubenfedern oder Tellerfedern angeordnet sein. Ebenso könnten zwischen Muttern 7 und Scheiben 2 Federn angeordnet sein.If the individual metal disks are not resilient or elastic, then between the sleeves 3 and 4, which can be screw sleeves, and the washers 2, coil springs or disc springs can be arranged. Likewise, springs could be arranged between nuts 7 and washers 2.

Die zentrischen Durchbrechungen der Scheiben 2 können verschiedene Form besitzen. Die Normalform ist rund. Es können aber auch ovale oder eckige Durchbrechungen vorliegen.The central openings of the discs 2 can be different Own shape. The normal shape is round. However, oval or angular openings can also be used are present.
